slskd was capped at one transfer per daemon, on the grounds that
Soulseek peers punish clients that ask for too much. That politeness is
per peer: two different users do not compete for anyone's upload slot.
So one slow peer serialised every other Soulseek download behind it.
The manager now takes a per-(provider, peer) lock before any slot, so a
grab waiting on a busy peer does not hold a provider slot another peer
could use, and the slskd default rises to 3, which now counts peers.
The help text says so.
Running grabs at once exposed the folder collision: slskd names a
download's directory after the remote leaf folder, so two peers'
"Greatest Hits" (or any two rips' "CD1") share one directory, and
collect finds files by name there. Grabs whose local folders overlap
now take a package-level lock per folder, in sorted order, keyed on the
full path because two clients can share one daemon.

A failed transfer failed the whole download. On Soulseek the usual
failure is one peer being offline or refusing, and a popular album has
several other peers offering the same folder; the ranked list that
names them was already held in m.results and nothing walked it.
grab now loops: when a candidate's transfer fails, or delivers too
little of the album to import, the next candidate is tried in its
place, up to three in all. Three rules keep that honest:
- Only a candidate auto-pick would itself have accepted is offered, so
a second choice clears the same match, quality and guardrail gates
as the first.
- On Soulseek the failure is the peer's, so every folder that peer
offered is skipped with it; elsewhere only the failed release is.
- A candidate the user picked by hand does not fall back. They chose
that copy, and quietly substituting another is a decision they did
not make.
The same change fixes auto-pick grabbing the wrong candidate.
AutoPickVeto judges the best candidate inside the user's guardrails,
but Start and Attempt then grabbed ranked[0] -- so when the overall best
was over the size ceiling, the veto passed on the strength of the
second and the first was downloaded anyway: the one copy the user had
said not to take unattended. autoPick returns the candidate the veto
actually judged.

Both per-provider cap tests spawned three `manager.grab` goroutines and
returned as soon as their assertions held. A grab outlives the
provider's Grab — it imports the staged files, releases the reservation
and writes the download's final state — so the test raced t.TempDir()'s
cleanup, which deleted the staging directory underneath work still
running. The failure is reported by the framework after the test has
passed, names no line of code, and reads as a flake:
`TempDir RemoveAll cleanup: directory not empty`.
It stopped being intermittent: 3 of 3 locally and every recent CI run,
where it failed `check` and therefore skipped `e2e` as well. Both tests
now wait for the goroutines they start, with a timeout so a stuck
transfer fails the test rather than hanging the package.
Verified 25 runs of the pair and 4 of the package under -race.
The durable "I asked for this" record was called Want, and the one-shot
search-and-grab attempt was called Request — names that didn't match
what either actually did. Want is now Request, and the old Request/Item
is now Download/DownloadItem, with a table-rename migration
(download_wants -> download_requests, old download_requests ->
download_downloads) safe against both fresh installs and existing data.
Every anchored manual download now upserts/reuses a durable Request
before running, so a "download now" that finds nothing is picked up by
the background reconciler automatically instead of just failing with
no trace — the gap that caused this session's repeated "no candidates
found" failures on the same album.
Also adds auto-download guardrails (file-size min/max with a preferred
target, allowed file types) that gate what the pipeline may grab
unattended, live-editable from a new settings section. The frontend's
wanted-view becomes downloads-view, with a new Downloads tab showing
attempt/transfer history that previously had no UI at all.

Ships the fresh-start schema cleanup: rebuilt explore catalog index
pipeline (dump import, artifact fetch/build, incremental listen-count
refresh), a new download subsystem (Lidarr/Prowlarr/qBittorrent/SABnzbd/
slskd/yt-dlp providers, staging, reconciliation, wanted list), and the
supporting schema/query/store changes across backend and frontend.
Also includes two smaller follow-ups: bump the central index's
rebuild-after cadence from 90 to 180 days, and remove the Explore
"library only" online/offline toggle entirely (frontend-only, no
backend counterpart) rather than carry unused UI/state.
